Synthesis of Thermally Stable and Highly Active Bimetallic Au-Ag Nanoparticle…

A general two-step approach has been developed for the synthesis of very small and sintering-resistant bimetallic gold-silver nanoparticles on inert supports including commercial silica and alumina. In this approach, gold particles were formed in the first step on amino-functionalized silica or alumina support. Our density functional theory (DFT) calculations on selected model clusters show …
